DESCRIPTION
The DG449 is a dual supply single-pole/double-throw
(SPDT) switches. On resistance is 38  and flatness is 2.6 
max over the specified analog signal range. These analog
switches were designed to provide high speed, low error
switching of precision analog signals. The primary
application areas are in the routing and switching in
telecommunications and test equipment. Combining low
power, low leakages, low on-resistance and small physical
size, the DG449 is also ideally suited for portable and battery
powered industrial and military equipment.
The DG449 operates either from a single + 7 V to 36 V
supply or from dual ± 4.5 V to ± 20 V supplies. It is offered in
the very popular, small SOT23-8 package.
